XHD Installation, Operation, and Maintenance Manual 29
Guideline Explanation
Check the alignment again after any mechanical adjustments. This corrects any misalignments that an
adjustment may have caused.
Attach the dial indicators for alignment
You must have two dial indicators in order to complete this procedure.
1. Attach two dial indicators on the pump coupling half (X):
a) Attach one indicator (P) so that the indicator rod comes into contact with the perimeter
of the driver coupling half (Y).
This indicator is used to measure parallel misalignment.
b) Attach the other indicator (A) so that the indicator rod comes into contact with the inner
end of the driver coupling half.
This indicator is used to measure angular misalignment.

2. Rotate the pump coupling half (X) in order to check that the indicators are in contact with
the driver coupling half (Y) but do not bottom out.
3. Adjust the indicators if necessary.
Pump-to-driver alignment instructions
Perform angular alignment for a vertical correction
Before you start this procedure, make sure that the dial indicators are set up correctly.
1. Set the angular alignment indicator to zero at the top-center position (12 o’clock) of the
driver coupling half (Y).
A unit is in angular alignment when the angular indicator (A) does not vary by more than
0.10 mm | 0.004 in as measured at 4 points 90º apart at the operating temperature.
2. Rotate the indicator to the bottom-center position (6 o’clock).
3. Record the indicator reading.
When the
reading value
is... Then...
Negative The coupling halves are farther apart at the bottom than at the top. Perform one of
these steps:
• Add shims in order to raise the feet of the driver at the shaft end.
• Remove shims in order to lower the feet of the driver at the other end.
